In a jungle where there are no street lights or any other artificial source of lights, I notice a black snake crossing the road.
How did I get sight of the snake?

He runs but never walks. Murmurs, but never talks. Has a bed, but never sleeps. And has a mouth, but never eats?

If an electric train is travelling south, then which way is the smoke going?

I am sometimes honest
Sometimes dishonest

It is a six-letter word.

The fourth second and last letter is payment.

Who is it?

How old is your son? asked a man to his neighbour. My son is five times as old as my daughter and my wife is five times as old as my son. I am twice as old as my wife whereas my grandmother, who is celebrating her eighty-first birthday is as old as all of us put together.

How old is the man's son ?

As easy as you can get into me, it is as hard to get out of me.

Do you know what I am?
